河北省夏玉米气候适宜度及其变化特征分析
Climatic suitability of summer corn and its changes in Hebei province
摘要
Abstract
Based on the daily climatic data and statistics methods, the climatic suitability model for summer corn (Zea Mays) during growing season was established, and its changing characteristics of the climatic suitability was analyzed. The results showed that the precipitation suitability degree was obviously lower than that of sunshine and temperature, and the variation coefficient of precipitation suitability was the largest. The temperature suitability during the grain filling period was the lowest and the variation coefficient was the largest; the sunshine suitability and precipitation suitability during the heading stage were the lowest and their variation coefficients were the largest. For the change tendency of climatic suitability, the sunshine suitability degree of summer corn decreased obviously during growing season (the ratio -0.047/10a), but the temperature suitability had little variation, and the precipitation suitability had no changing trend from 1981 to 2010. The climate suitability degree decreased at 0.015/10a during the seedling stage which caused by the decline of temperature and sunshine suitability, and the climate suitability degree decreased at 0.024/10a during the grain filling stage which caused by the decline of sunshine and precipitation suitability.关键词
